PixVerse API vs Replicate video models

PixVerse API

V6 at about $0.04 a second at 720p, with audio and clips up to 15 seconds. Plan prices and the dollar value of a credit sit on a JavaScript-only billing page.

Replicate video models

One bearer token reaches more than twenty official video models at published per-second prices, each with a typed input schema, and failed runs aren't charged. Tokens have no scopes or spend cap, no SLA is published, and the terms let Replicate withdraw any model without notice.

PixVerse API

1. Generate a new UUID for Ai-trace-id on every new submit. Reuse it only to fetch the same job again
2. Poll the result endpoint. Status 1 is done, 5 generating, 7 moderation failure, 8 failed
3. Moderate prompts before calling. Repeated status 7 results can suspend the key
4. Use model v6 or c1 for new work. Older model tables still sit in the docs

Replicate video models

1. Call official models at POST /v1/models/{owner}/{name}/predictions with no version, then poll GET /v1/predictions/{id} or pass webhook. Video jobs usually outlast the 60-second Prefer: wait window
2. Download the output file within the hour. API predictions lose inputs, outputs and logs after 60 minutes
3. Read the model's price tiers before setting resolution, mode or generate_audio. Kling 3.0 runs from $0.168 to $0.42 a second and Veo 3.1 doubles with audio
4. Send Cancel-After on every create. There is no idempotency key, so a blind retry is a second paid video
5. Keep credit above $20 or enable auto-reload. Low balances are throttled, and granted credit with no card is held to 6 requests a minute
